High-Entropy Oxides

Here we study chemically complex, high-entropy oxides and characterize them mainly using neutron and X-ray diffraction and total scattering to map how multi-cation disorder and strain fields shape their magnetic landscape. By focusing on how scattering signatures evolve with temperature and field, and comparing to reported macroscopic responses, we distinguish conventional glassy freezing from genuinely frustrated collective states.

Statistical and mean-field models then link the enormous cation-configuration space to experimentally observed scattering signatures. The broader goal is to identify disordered oxides that host robust, tunable magnetic functionalities while remaining compatible with realistic synthesis and device constraints.
